Begonia plant named ‘Garden Angel Silver’

ABSTRACT

A new and distinct form of  Begonia  plant characterized by maple-like palmately lobed leaves with showy interveinal silvering, red leaf backs, a bushy habit, small clusters of large cherry pink flowers in winter to early spring, hardy to USDA Z7, and excellent vigor.

Botanical denomination: Begonia hybrid.

Variety designation: ‘Garden Angel Silver’.

Parentage: Begonia ‘Benitochiba’×Begonia grandis subsp. evansiana.

Comparison to siblings Begonia ‘Garden Angel Plum’ U.S. application Ser. No. 13/986,507 and Begonia ‘Garden Angel Blush’ U.S. application Ser. No. 13/986,504.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Begonia, of the family Begoniaceae, and given the cultivar name, ‘Garden Angel Silver’. This plant originated from planned breeding program for a colorful series of landscape Begonia. The new cultivar originated from a cross between Begonia ‘Benitochiba’ (unpatented), as the seed parent, and Begonia grandis subsp. evansiana (unpatented), as the pollen parent. This selection is uniquely characterized by:

-   -   1. maple-like palmately lobed leaves with showy interveinal         silvering,     -   2. red leaf backs,     -   3. a bushy habit,     -   4. small clusters of large cherry pink flowers in winter to         early spring,     -   5. hardy to USDA Z7, and     -   6. excellent vigor.

Compared to the seed parent Begonia ‘Benitochiba’, the new cultivar has leaves that are silver rather than purple blushed and are palmately lobed rather than palmately compound. The new cultivar is hardy rather than being a tropical plant.

Compared to the pollen parent, Begonia grandis subsp. evansiana (common name the Hardy Begonia), the new cultivar has leaves that are palmately lobed rather than no lobes and with strong interveinal silvering rather than no silvering.

Compared to Begonia ‘Garden Angel Plum’ (U.S. Plant patent application Ser. No. 13/986,507), the new cultivar is silver interveinally rather than being all plum interveinally and is shorter.

Compared to Begonia ‘Garden Angel Blush’ (U.S. Plant patent application Ser. No. 13/986,504), the new cultivar is all silver interveinally rather than having plum-red violet blush.

The new variety has been reproduced only by asexual propagation (cuttings and tissue culture). Each of the progeny exhibits identical characteristics to the original plant. Asexual propagation by micropropagation as done in Canby, Oreg., shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations. The present invention has not been evaluated under all possible environmental conditions. The phenotype may vary with variations in environment without a change in the genotype of the plant.

DETAILED PLANT DESCRIPTION

The following is a detailed description of the new Begonia cultivar based on observations of nine-month-old specimens grown in one gallon containers inside a cool greenhouse in early January in Canby, Oreg. Canby is Zone 8 on the USDA Hardiness map. Temperatures range from a high of 95° F. in August to 32° F. in January. Normal rainfall in Canby is 42.8 inches per year. The color descriptions are all based on The Royal Horticultural Society Colour Chart, 5^(th) edition.
